Abstract
Pseudorandom numbers are generated for telephone dialing in telephone call management systems by selecting a range of numbers to be dialed, successively randomly generating numbers within that range, comparing each randomly generated number as it is generated with numbers previously generated and recorded or called. When a new randomly generated number matches a previously generated number, a further number is generated and the compared. When no match is encountered, the new number is recorded or called. After recording or calling a predetermined amount of numbers within the range, remaining numbers to complete the range of numbers are selected sequentialy from an array of numbers. The final numbers are recorded or called in sequence, but the steps between the final numbers vary randomly according to the random generation of the numbers in the first part.
